Abstract:
   The process leading to the formation of stars is among the most complex studied by astronomers to date. I discuss several recent progresses: 
    Kinematic information: Data from the Gaia satellite have enabled us to map the gas with unprecedented details. Using Gaia data, we provide a vivid picture of the structure evolution of the Milky Way disk where the effect of shear, stellar feedback and can be studied.
    Computational approach: The star-forming clouds have complex structures, and I will discuss how modern computational methods can quantify the structure of clouds and reveal the role of gravity and tides.
    Analytical models: The most accurate way to describe natural phenomena is through analytical models. I introduce a new model that describes modifications to stellar mass in non-stationary conditions, which explains the formation of massive stars in the universe.
